So what are a few things you guys would love to see in a MMO? I will list a few of mine and expand later.

A number 1: A Sci-fi MMO that doesn't fall back on magic or religion and has no elves Any "fantasy" elements are focused through a tech lens. Yes, I have tried "Eve".

A Fantasy MMO where Rogues quests play out like "Thief: The Dark Project" and you get meaningful XP for said quests. Rogue advancement based on those quests and doing things like; picking pockets, open chests or locks, disarming traps, entering homes in cities undetected and stealing etc.

An MMO based on Whitewolf's "Vampire: The Masquerade". EDIT: Thought I would expand here. Have playable characters be Hunters, Mages, Werewolves and Vampires.

Classes that have a viable option to solo and do better in groups. You should be able to solo when you can't; form a meaningful group, have little time, or don't want to be stuck in a poor group if others aren't available at that time.
